• MOULDED  WIRE-WOUND   RESISTORS •
USED IN OLDER MODELS FROM 1936 TO 1940s

Moulded Wire-Wound Resistor
   PHILCO introduced a new type moulded resistor [March, 1936, Philco Serviceman] to replace the flexible wire-wound resistors formerly used. This moulded resistor is similar to the small mica condenser used in current [1936] models and has the advantage of being moisture and "short" proof.

   The resistance wire is wound on a special heat-resisting strip with the respective wire ends attached to eyelets in each end of the strip. The connecting leads are also clamped under these eyelets. The strip is then placed in a mold and a special bakelite composition applied. These resistors, which carry standard R.M.A. color code, come in the following sizes:
